AMS-02

Information gathering. Unlock Secrets of the Cosmos

AMS-02 is a multipurpose magnetic spectrometer designed to measure elementary particles and nuclei to the TeV region. In the five years since its installation on the International Space Station, it has collected more than 90 billion cosmic rays. Some of the unexpected results and their possible interpretations will be presented.

The Commissioning of the ATLAS

Atlas Experiment :Tile Calorimeter Barrel

The commissioning of the ATLAS detector with physics data started more than three years ago with cosmic rays. This has enabled us to put in place the full operation chain, from the trigger and data acquisition up to the analysis all over the world. Thanks to this intense commissioning campaign, ATLAS was ready to collect data already during the first day of LHC single beam operations on the 10th of September in 2008.

 There is no doubt that I would move fast forward to the culmination of everything that is a part of the atlas experiment to have said the final result is what is to be gained by measure. The Calorimeter view just seemed natural as the going on of Glast,  now called Fermi would have shown it's own construction as a necessary element of that measure in calorimeter design. So of course jumping ahead one needed to carry certain assumptions, and for me this was about the cosmic particle events that lay at the foundation of the universe in it's informative style as reductionist in nature.

There is a little confusion on my part here about the simultaneous view that what is in the pipeline has a strong correlation to what we seek of,  in cosmic particle collisions. The energies involved,  as decay products. So as I looked at this article and the phenomenological correspondence necessary I needed to understand that effects of such operations,  current in the cosmos could have somehow contaminated the results they were seeking through controlled processes. So how was this done is the issue here and how such data cannot be influenced by what is currently happening in the cosmos.

As a layman it was of interest that my developing perspective about the cosmos at this scale sought some kind of revelation in the way research would have been done experimentally. So this was a challenge to me that I could see the scale at which the cosmos picture was developing microscopically on a large scale could have been part and parcel exemplified in this research as the cosmological view. It just seemed natural to me the effect of what was happening on earth was somehow translated in how the earth itself sat in the cosmos as a participant bathed in the cosmos glory.

In a sense I have felt belittled by the idea that my seeking of the workings of the cosmos would have fell to such materialistic views. Of course I want to know how it all works.  But truly this is the way I am sure that would lead to the understanding of something very important about the way in which we can view the universe. At some point,  there is an exchange taking pace about how such matters form, and there is no other way in which to derive this but to further dissect the nature of particulate expression but by energy disposition?

COSMOS:AIRES Cosmic Ray Showers

Throughout the course of my research there has been a connecting thread that has brought me to certain conclusions about matter states as they exist in the cosmos, but by identifying the particulates of the realty in which we live. So in a way it is necessary to observe that nature we are seeing as so obvious in our observation on a fundamental level, can go much deeper as we implored the the use and need of the spectrum in this wider view of the cosmos. The backdrops necessary in determining what the energy is saying as we record the events in the calorimetry design,  how ever this is constructed.

In this same way as cosmic particle collisions are derivative of the events in the cosmos, for Atlas research,  CMS serves to support Atlas, and vice versa?? :)

The primary goal of this 3‐day workshop is to educate the LHC community about the scientific utility of likelihoods. We shall do so by describing and discussing several real‐world examples of the use of likelihoods, including a one‐day in‐depth examination of likelihoods in the Higgs boson studies by ATLAS and CMS.

The workshop will start with two pedagogical lectures that introduce likelihood concepts and terminology. These lectures are followed, in the afternoon of Day 1, by a moderated discussion that focuses on the concepts and issues raised in the lectures. Day 1 ends with several presentations that illustrate the use of likelihoods in Higgs and Beyond the Standard Model (BSM) research. The goal here is to get feedback from researchers who have used Higgs and BSM results in their work.See: Likelihood for the LHC Searches

You know analogies are important in that they can bring a lay person some clarity in helping to understand what s going on in the world of science. As a blogger I have attach myself to some scientists who have been more then willing to share this aspect of them-self with the world. I do not know of a more honorable thing a scientist can do but by taking this time to help the public.

XKCD Significant-Speed of Light Issue?

You got to love it when correlations can be made, and a thank you to the ICECUBE Blog

If the histograms and data are exactly right, the paper quotes a one-in-ten-thousand (0.0001) chance that this bump is a fluke. That's pretty small; although bear in mind that lots of distributions like this get plotted. If you plot 100 different distributions, the chances become about one in a hundred (0.01) that you'll see something odd in one of them. The Tevatron goes bump

So what about the Missing Energy?

"Death, so called, is but older matter dressed
In some new form. And in a varied vest,
From tenement to tenement though tossed,
The soul is still the same, the figure only lost." Poem on Pythagoras, Dryden's Ovid.

It is unfortunate to have endured the constant flutter of disbelief(cry of pseudoscience) as to what is possible in a given space, that we can say that we do not really have all the facts to it's understanding, yet, to know that in this region, new physics will be produced.

It is also unfortunate to have observed a whole generation of string theorists who have undergone this constant rebuttal and berating over and over again while standing strong to the "educative values" undermined by those who saw no benefit too. You maintained the perseverance of a "thought domain that cover regions within the valleys" to be speaking about a time just after the big bang. How would the normal population of scientists know this?

Thanks to the high collision energy and luminosity of the LHC, the ATLAS detector will be capable of revealing the existence of extra spatial dimensions in some substantial region of parameter space. The talk will summarize recent studies from the collaboration on different possible signals predicted by models where the dimensions are "large", where they are of size ~TeV^-1 or where they are "warped". These signals include direct emission of Kaluza-Klein states of gravitons, virtual effects of graviton exchange and gauge boson excitations. We shall also discuss the possibilities of observing black holes. mini review for search of eXTRA Dimentions

Now this question is an important one to me, because it is based on the amount of energy used in the collision process, and what is to come out of that collision process as tracks, adds up to so much energy. If these two numbers do not equal in parity then where has that extra energy gone?

This has always been a fundamental question to me of where I thought "new physics was to be found" and to have Tammaso Dorigo confirm this is quite a statement indeed of what is leading perspective in terms of what is to be measured and what is going to be measured in the proposed LHC experiments.

Missing Energy Kicks New Physics Models Off The Board

The signature of large missing energy and jets is arguably one of the most important avenues for the study of potential new physics signatures at today's hadron colliders.

The above concept marks an interesting turn of events: the years of the glorification of charged leptons as the single most important tools for the discovery of rare production processes appears behind us. The W and Z discovery in 1983 by UA1 at CERN, or the top quark discovery by CDF and DZERO in 1995 at Fermilab, would have been impossible without the precise and clean detection of electrons and muons. However, with time we have understood that missing energy may be a more powerful tool for new discoveries.

Missing energy arises when a violent collision between the projectiles -protons against antiprotons at the Tevatron collider, or protons against protons at the world's most powerful accelerator, the LHC- produces an asymmetric flow of energetic bodies out of the collision point in the plane orthogonal to the beams: a transverse imbalance. This is a clear signal that something is leaving the detector unseen. And it turns out that there is a host of new physics signals which can do precisely that.

A large amount of missing transverse energy may be the result of the decay of a leptoquarks into jets and neutrinos, when the latter leave undetected; or from the silent escape of a supersymmetric neutral particle -the neutralino- produced in the chain of decays following the production of squarks and gluinos; or it may even be due to the escape of particles in a fourth dimension of space -an alternative dubbed "large extra dimensions". see more in linked title above)

Now this is the thing that has troubled me most about scientists who are working and in the know, had not realized the necessity of pushing perspective back to a time to the first moments of the big bang(not just Steven Weinberg's first three minutes but of the microseconds just after the big bang) in order to understand what we are working on in terms of unification, and of where the products of this missing energy will spring forth from, as we move forward in the experiments to come.

The understanding then has always been in what is in that missing energy, to determine what new physics shall be, that such understanding was already there for the string theorist in their considerations. The contact point has already been defined for them, and reached two extremes. There is a reason why the missing energy escapes.

You had to know already where and what this "contact point meant" and what was to come out of it to know that dynamical qualities could exist in the big bang and where this big bang resides in the cosmos. That such energies can be reached there now. This required us to know that local events in the cosmos could contribute to the very nature of the cosmos and the state of the cosmos in the now. Like some cosmological constant "hidden and growing" in Omega.

To know that the dissipative results from micro collisions decaying fast too, did not mean we would be running short of the elements of this new physics either. It left it's remnants all around us to know that what can come out of such a collision point is not the story of the FLashForward scenario, but of things that travel through the earth to meet Gran Sasso and the likes. It was a whole plethora of particle disseminations that left missing energy around for us to explore in potential as some fictional substrate of the reality of nature that had not been seen before.
